THAT’S THE TICKET: Former U.S. Sen. Scott Brown, right, posted a picture of himself yesterday with U.S. Sen. Marco Rubio, followed by a tweet that read, “Maybe.” A reference to a 2016 GOP ticket, perhaps?

When Scott Brown posted a picture of himself with a beaming U.S. Sen. Marco Rubio (R-Fla.) yesterday, the social media site lit up — especially after he followed it up with a one-word addendum: “Maybe.”

Maybe a GOP ticket in 2016?

The cryptic message forced the former Bay State senator to tweet an explanation.

“In the form of an update, as i was rushing to get a plane I responded — maybe to a charitable appearance request. That’s what I get 4 rushing,” Brown wrote.

The hashtag #blockedbyscotto even began trending, hinting at some damage control.

“Hmm. What did you do to get blocked?” fellow former U.S. Sen. William “Mo” Cowan tweeted to one person claiming he got blocked and asking Cowan to promise he wouldn’t do the same.

Rubio, who has presidential aspirations, dropped into the Hub for a fundraiser for his political action committee where he told attendees he was hoping to support “four or five candidates,” according to Bay State House Minority Leader, Rep. Brad Jones, who attended the event.
